, The improved mechanism-isconstructed so a as to adapt it to the'scrubbing of delicate Vfabrics, as for example silk stockings without danger of damaging the structure thereof and where desired to apply acleaning;

substance thereto during the'scrubbing action. In the present embodiment, the'scrub hing action is accomplished'by the provision of a pair of wheels or rollers mounted. in

superposed peripheral contact one of the wheels being positively driven and the other wheel frictionally driventhereby. The upper wheel is mounted to rest by restricted gravity upon and in yielding contact, with the lower one so as to accommodateitself to any undue pressure exerted by the fabric being cleaned as it passes between the wheels and-the peripheriesof the wheels are covered with yielding material whichmay'be of an absorbent nature adapted, to, satisfactorily feed the cleaning material. One ofv the wheels may be mounted to extend or dip into 7 a. receptacle containing such' cleaning sub.- stance and deliver the sameto the fabric being cleaned and to 'theperipheral covering of the other wheel. 7 v
